naPRovEMEN-r IN CORN-CULTWATORS.

The VScheduleliefert-'ellto in these Letters Patent and making part of the same.

. Be it known that we, SOLYMAN BELL and GEORGE W. BRONSON, of the county of LaSalle, andl State of Illinois, have invented a newand useful Improvement on a Machine for Gultivating Corn; and we do hereby declare that' the following is fa full, clear, end exact description of the construction and operation of the same,

reference being had tothe 4annexed drawings, making la part of this specicatiomin which- Figure l is a plan view.

Figure 2 isa side view. i

Figure 3 is a rear view of gopher-frame.

Figure 4 is a side View of gopher-frame.

`lo enableothers to make anduse our improved machine, we will proceed to describe its coustructionand operation;

l We.constructav frame-work carriage, composed of woodiboltedV together, as shown in iig. 1, side-pieces A and B, cross-pieces 0 and D, braces E and F, and

rear bar H, on which is placed a driveids seat. ,l Y' This frame is furnished with a`- tongue,G, whiletrees,&c., and is supported ou wheels I and K.

To this frame-work"ca`uiage the beams, shield, and

` handles, are attached as follows:

` l.` The Beams. t 'lhe iron rod a, a, g. 2,l is attached Ato the front corners of the frame at point b, and strengthened by brace c c. Upon this rod is placed the adjustable collar-clevis d, shown at large, fig. 2. v

This clevis is furnished with collar and set-screw by which it can be readily made fast at any place on the rod aa, so as notto slide upor down, while it can turn toward either side freely. The forward end of the beam e'e is inserted in the rear end or jaw ofthe clevis and fastened with a bolt whichallows the real end of 'beam to-be raised and lowered at pleasure. The depth of the shovels can be easily regulated, therefore, by loosening the adjustable collar-clevis upon the ,rod au, and rais-V ing or lowering at pleasure, and then tasteningtoplace bythe set-screw in the collar.

` 2. Standards.

` The standards f are attached to the beam by bolts g, and strengthenedbybraces h. h'. he tops of the long standards are furnished with handles, a'. t, fastened lbyT-boltand socket, 7c It. v 1 l To the bottom of standards are attached the diamond-shapedshovels Z Z.` f 1 y The two long standards are also connected as follows An eye-bolt is put through each standard atthe point q, with nuts'ou each side of standards.` These eye-bolts are connected by an iron rod with aneye at each end.

By this connection `the two beams are keptat anni# form distance apart,` and this distance may be graduated tosuit `theuoperator bymeans of `the screw and nuts each side of standard, while at the same time each ,beam and theattached shovels can have an independent motion up and down.

3. The Handles 'i The handles, as before,stated, are fastened by bolt -and socket to the tops of the long or forward standards and` pass through staples 'm m, in which they work loosely. These staples are inserted in cross-.bar of frame eD.. The beams are furnished with hooks n n# s When itis desired to raise the shovels entirely out of the ground, and carry them clear of it, the rear ends ofthe handles are Vraised by the driver. This raises the rear end of beams, and lowerl` front ends'of handles, so that they can be inserted in the hooks n n,

and the whole .cultivator will theuride 'clear of the ground.

c 4. The cylinder-shale. i

This shield is attached to the tongue by the rod=o o, whichis furnished atthe rear end with a spring, p, which causes the shield to hug the ground, .t y

The roda o is attached 'to the tongue by a bolt, q,

whichallows the yshield free lateral motion.

The rear end ofshield is attached to the long standarde by means of chains, so that the ,shield can-not have any lateral motion, except that ofthe standards and shovels.

' The driver of themachine can therefore give to the `standards such lateral motion as he `may desire, by. means' of the handlesi t, and this motion will, through the chains,.be communicated to thecylindric shield,

i or the driver may give a 'lateral vmotion to the shield .with his foot, and this same motion will, by means of the chains, be communicated to the standards and shovels.

5. The Dmmmdfshwen:

lThe cultivator-shovelsV are cut away at the top in the same `shape as at the bottom, so as to be of diefV mondfshape.

This allows the earth topass over the tops of the shovels, instead `of forcing it toward each side of them, and leaves the ground level, instead of in grooves. It

also makes the draughtof the machine much easier, and renders it more easy to handle. v

A separate beam, as shown in' figs. 3 and 4, furnished Vwith a gopher, Irupon\ the forward or long, standard, and adiamond-shovel on the short oi rear standard, is v inserted in the machine in Vthe place of the beam furnished with diamond-shovels throughout, whenever it is desired to use the gopher in combination with the shovels.

These beams are attached to the frame by the adjustableecollar clevis, and to the rest of the machine inthe same manner as the `beams first herein descr ibed, except that the long forward standards are connected by'aibow,y as shown in figs. 2 and 3, instead of the rod hereiubefore described.

What we claim as our invention, and desire to secur by Letters Patent, is as follows: g

1. The method by which the half-cylinder shield is 4. The'wholemaohine, as a combination of gopher attached rio the tongue and standards, by spring rod and ouitivaoor, operating as hereinbefore more particand chains, as above described. ularly described.

2. The adjustable oollar-clevis, by which the beams SOLYMAN BELL.

are attached to the frame. GEORGE W. BRON SON 3. The manner of attaching the handles ofthe Ina- Witnesses: chine to the standards, and to the frame by means of ARTHUR GRAY, the loose staples and bolt and socket. WILLIAM GRAY.
